title: Improved fluorometric-iodine method for determination of aflatoxin in corn.
abstract: Several innovations in the fluorometric-iodine (FL-I) method for determining aflatoxin in corn made the procedure faster and more convenient than the original method. Ground corn was packed into a chromatographic column and the aflatoxins were extracted with methylene chloride. Sep-Pak C18 cartridges were used for sample cleanup. A 5 min thin layer chromatographic slide analysis confirmed the presence of aflatoxin, which was quantitated by fluorometric determinations of the iodine derivative of aflatoxin B1.
